$1 trillion spread over, say, 16 years is $62.5b/year, or 0.45% of that economy, even assuming ongoing stagnation.
Add $2.5b annually to the front years of that for the $20b in long haul transmission capacity required for 20% wind power ... it zooms up to 0.47% for the first half of that. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
